Clarification of Confusion in Level Scheme of ¹²⁴Cs

Low-lying and high-spin states of ¹²⁴Cs are studied through the ¹¹⁶Sn¹¹B,3n)¹²⁴Cs reaction at a beam energy of 45MeV. Several new linking transitions are observed, including three transitions between the yrast and πh_11/2νd_3/2 bands and two transitions between the yrast and π h_11/2ν(d_5/2,g_7/2) bands. These transitions fix the excitation energy of the yrast band and its decay path, and confirm the existence of eight E1 linking transitions between the yrast and π h_11/2ν(d_5/2, g_7/2) bands observed before. These E1 linking transitions infer the octupole correlation in ¹²⁴Cs. The decay paths of the yrast band are investigated, and discrepancies in the level scheme of ¹²⁴Cs in the latest two studies are clarified. The reason for the discrepancies is discussed. A new decoupled band is established and temporarily assigned as the unfavored signature partner of π h_11/2νd_3/2 configuration.
